CPT code 64657 denotes surgical removal of an entire baroreflex activation therapy (BAT) system, encompassing both the lead(s) and the pulse generator. This procedure is relevant nationally as the use of implantable neuromodulation devices grows for treatment-resistant cardiovascular and autonomic conditions; accurate coding supports appropriate claims processing, device-tracking, and quality measurement. The code captures a discrete explantation service distinct from partial removals or generator-only procedures.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coding intent, clinical context, and common billing considerations for device explantation. The publication outlines expected service settings (operating room, ambulatory surgery center, or inpatient surgical suite) and clarifies that this code represents complete system removal.

The piece provides benchmarks and policy-relevant content such as typical utilization patterns, documentation elements that support medical necessity, and alignment with surgical service lines. It also highlights where “Data not available in the input” applies for fields not supplied. This national-level summary aims to inform coding professionals, revenue cycle staff, and clinical leaders about the purpose of CPT code 64657 and the practical implications for billing and administrative workflows.
